t.rast.series: allow multiple methods/output
|Reported by:||sbl||Owned by:|
After r.series received support for multiple methods/outputs in one run, computing multiple STDS statistics with t.rast.series could get a speed up if this is handed down to ths module. Attached a diff where I also tried to incorporate changes in the test coverage, but I have no experience with the test-suit. So manual testing of the diff would be welcome. When applied, also manual should be updated...
